6 Demo scripts
If you want to see the live images, we recommend using a display on the Polis Board (for example 10” 1280x800 Display KPEB-AV-10-100.A0)
There are 3 sub directories with demo scripts for the cameras:
- gstreamer-examples
- v4l2_c-examples
- opencv-examples
Notes: Remove the qt-demo at the first start. With the \gstreamer-examples\remove_qt_demo.sh script, else the qt-demo is alway present on the display.
6.1 GStreamer scripts
After login, change into the directory: \gstreamer-examples\..
cd gstreamer_examples <ENTER>.
Now you can start working with the GStreamer demo-scripts.
Start the scripts with den word phrase "col" or "bw" depending on the connected camera color type.
- _cam-fbdev_1280x720.sh – scripts, show a livestream on display
- _cam-save_jpg_full_res.sh – scripts, save a JPG File in this directory
- _cam-save_raw_full_res.sh – scripts, save a RAW File in this directory
- func.sh – script, detect the camera typ and define the parameter for the scripts
- remove_qt_demo.sh – script, remove the qt-demo from autostart
- turn_off_on_wayland.sh – script, turn of/on if wayland necessary or not
Subdirectories:
- more_ar0144_scripts: contain more scripts for the VM-016 camera series (v4l-ctrl_ar0144.txt, list the v4l2-controls for this camera)
- more_ar052x_scripts: contain more scripts for the VM-017/117 camera series (v4l-ctrl_ar052x.txt, list the v4l2-controls for this camera)
- vpu_enc_dec_scripts: contain scripts how use the vpu-encoder (e.g networkstreaming or save H.264 streams)
